Problems with upgrading to xubuntu 9.04

[richardy]

Hi,
I have just tried upgrading from xubuntu 8.10 to 9.04 via the inbuilt software upgrade tool and everything seemed to go fine until i restarted when i got the following error:

"No Exec line in the session file: xfce4. Running the gnome failsafe session instead"

I tried to run the /usr/bin/xfce-session file from the command line and got the following response (see below).

Any help with this would be much appreciated.

Cheers.
